3 Claims.

The present invention relates to devices for preventing the reiilling of bottles or other liquid containers.

Devices of thisvcharacter heretofore employed embodyan intricate structural arrangement involving an appreciable number of complicated parts thereby incurring a costly manufacture and often resulting in faulty operation which renders the device ineiiectivefor the purpose intended.

In view, of these disadvantages it is the primary aim of this invention to provide-a non-rellable bottle consisting of a minimum number of parts, each partbeing of comparatively simple form and adapted for rapid manufacture and assembly so as to present a device which may be produced on a relatively economic basis.

Another object resides in providing a refill preventive device having a slide valve member mounted therein for instant and dependable action upon moving the container to either pouring or upstanding position and serving to positively assure against admission of liquid into the container although at the same time permitting rapid decanting therefrom when the bottlev is tilted for pouring.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application.

In the drawing:

Fig. 1 is a side elevational view of the device attached to a bottle.

Fig. 2 is a central sectional view thru same taken on line 2 2 of Fig. l, the bottle being in upstanding position.

Fig. 3 is a view similar to Fig. 2 but showing the bottle in pouring position. Y

Fig. 4 is a transverse sectional view thru th devicetaken on line 4-4 of Fig. l; and

Fig. 5 is a perspective View of the sleeve valve member apart from the device.`

Reference is now had to the accompanying drawing for a more detailed description thereof in which the numeral 6 indicates a suitable cas- I ing preferably'of cylindrical form andV being (ci. eis-30) Within the casing and depending co-axially from the nozzle ll is disposed a cylindrical member or tube II having its bottom portion I2 constricted to define an aperture I3 therein. Portions of the cylindrical Wall of the tube II are 5 omitted to present a plurality of parts I 4 thru which liquid may pass into the pouring spout 1.

A second tube I5 is also retained within the casing 6 in substantial co-axial relation and extending toward the tube I I. The tube I5 is car- 10 ried on the casing 6 preferably by having formed at the lower portion thereof a radial flange I6 disposed at its.Y periphery in a stepped formation of the casing to be held thereby against the gasket il). It will be observed that the 15 free end of the tube I5 terminates in a substantially fiat end I'I and in spaced relation to the end of the tube II.

A sleeve valve I8 is slidably retained within the casing 6 being guided for sliding movement 20 by engagement at its respective ends with the tubes II and I5. The valve I8 is preferably of cylindrical form and includes an abutment or iniperforated partition I9 disposed intermediate the ends thereof. The cylindrical Wall of the valve I8 has provided therein a series of ports 2E) preferably disposed slightly below the partition i9. The lower end of the sleeve valve I8 is turned outwardly to provide a radial flange 2| the periphery of which is disposed to slidably contact the interior of the casing 6.

As aforeindicated the sleeve valve I8 is'guided for sliding movement by the tubes II and I5 so that in normal upstanding position of the bottle as shown in Fig. 2, the partition I9 thereof rests against the flat end Il of the tube I5. In this position the ports 28 overlie the tube I5 and are thus closed thereby against passage of fluid..` As the bottle is tilted for pouring the sleeve valve i8 slides to the position illustrated in Fig. 3 until the partition I9 engages thevbottom I2 of the tube II, and the ports 2l] are disposed beyond the tube I5 to permit passage of uid therethru. It will be observed that the upper portion of the sleeve valvel8 presents a cylinder in which the tube It acts as a piston. During the opening movement of the valve I8, the air or liquid within this cylinder is discharged thru the aperture I3.

As indicated by the arrows in Fig. 3, the der canting of liquid from the bottle 8 will be effected "0 by passage of the liquid thru the tube I5 and thence thru the ports 2E! into the annular chamber within the casing S from which the liquid passes thru the ports Ill Vand out of the pouring spout ,1. It will be observed that the liquid passing thru a non-rellable device assumes a substantially stream-lined path thus assuring an even and continuous pouring action. This effect is had in that the particular arrangement of the device permits the formation of the ports I4 and 20 of a substantially large free area.

When the bottle is raised to upstanding position the valve I8 returns by gravity to the position shown in Fig. 2. During this action, however, a substantial portion of the liquid remaining in the casing 6 is returned to the bottle 8. A portion of this liquid, however, is retained within the tube Il from which it passes thru the aperture I3 to within the upper portion of the valve 8 so that the weight of this entrapped liquid further serves to close the valve I8. The ange 2I at the lower end of the valve I8 also functions in a similar manner in that a portion of the liquid remaining in the casing 6 rests on the flange 2l to assist in the further closing of the valve I8.

It is to be understood that this improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not aiect the spirit of the invention nor exceed the scope thereof as eX- pressed in the appended claims.

`What is claimed as new is:

1. A non-rellable bottle device comprising a casing, a pair of co-axial tubes extending toward each other in said casing to present a passage for fluid therethru, and a sleeve valve slidably carried on said tubes and having an abutment therein adapted to close one of said tubes to prevent passage of liquid therethru.

2. A non-refillable bottle device comprising a casing having a spout, a first tube depending into said casing and having ports therethru, a second tube carried on said casing and extending coaxially toward said first tube, and a sleeve valve slidably carried on said tubes and having an abutment intermediate the ends thereof adapted to engage the free end of said second tube to close same against the passage of fluid.

3. A non-rellable bottle device comprising a casing having a spout, a rst tube depending into said casing and having ports therethru, a second tube carried on said casing and extending coaxially toward said rst tub-e, and a sleeve valve slidably carried on said tubes and having an abutment intermediate the ends thereof adapted to engage the free end of said second tube to close same against the passage of fluid, said sleeve valve including a radial flange slidably engaging said casing.
